GeForce GTS 250 1GB vs Radeon HD 3870 X2 1GB

Intro

The GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 RAM is set to run at a frequency of 1100 MHz on this particular model. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare that to the Radeon HD 3870 X2 1GB, which has a clock speed of 825 MHz and a GDDR4 memory frequency of 1126 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It features 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3870 X2 1GB, in theory, should perform much faster than the GeForce GTS 250 1GB overall. (explain)

Radeon HD 3870 X2 1GB 144128 MB/sec
GeForce GTS 250 1GB 70400 MB/sec
Difference: 73728 (105%)

Texel Rate

The GeForce GTS 250 1GB will be a lot (more or less 79%) better at AF than the Radeon HD 3870 X2 1GB. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
Radeon HD 3870 X2 1GB 26400 Mtexels/sec
Difference: 20832 (79%)

Pixel Rate

The Radeon HD 3870 X2 1GB is much (approximately 124%) better at anti-aliasing than the GeForce GTS 250 1GB, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 3870 X2 1GB 26400 Mpixels/sec
GeForce GTS 250 1GB 11808 Mpixels/sec
Difference: 14592 (124%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
